The subject of this graduation thesis was pulse frequency modulation. The thesis
consists of five chapters. Introduction to the theory of modulation is the first chapter,
here it is defined what exactly modulation is and what are the general types of
modulation. The next chapter consists of pulse modulation techniques and the summary
of three most popular and most used pulse modulations (PAM,PWM,PPM) and their
mutual comparison. One whole chapter is devoted to the theoretical background of
pulse frequency modulation. Various realization methods of pulse frequency
modulation are discussed here. The last chapter is of practical nature and it focuses on
the hardware implementation of a pulse frequency modulator and it's simulation results.
